Memory to repair will depend more on total inodes on the system etc, not
so much the absolute size of the filesystem.
The defaults are defaults for a reason; they are updated when warranted,
and unless you have a specific issue with them, it's best to just stick
with that.
IOW, if best practices warranted different tuning for a generic 10-16TiB
filesystem, then the defaults would need to be updated, rather than
offering hints 'n' tips on mailing lists. :)
